Abstract:
Hybrid Automatic Retransmit ReQuest-Acknowledgment (HARQ-ACK) index mapping and uplink resource allocation is performed and controlled for channel selection transmission. A method for transmitting HARQ-ACK information to an eNode-B (eNB) by a User Equipment (UE) includes identifying KPCell as a number of downlink subframe(s) of a Pcell associated with an uplink subframe and identifying KSCell as a number of downlink subframe(s) of an Scell associated with the uplink subframe; generating Discontinuous Transmission (DTX) response information for a cell having a smaller number of downlink subframes between the Pcell and the Scell; generating HARQ-ACK information including the generated DTX response information and response information on data received by the UE from the eNB; and transmitting the generated HARQ-ACK information to the eNB through the uplink subframe.
Abstract:
Provided is a method for allocating a resource for hybrid ARQ information, which is transmitted to a downlink, in a wireless communication system. The method for a transmission point transmitting the hybrid automatic repeat request (ARQ), includes: transmitting to a terminal an index of a group to which each of the terminals belong, along with information on a physical resource block to which an uplink data channel is allocated, and downlink control information for delivering circulation delay information of a reference signal, which is for demodulating an uplink; and transmitting the hybrid ARQ information, which includes whether the uplink data channel that has been transmitted is received, through a resource which is determined on the basis of the information on the physical resource block to which the uplink data channel is allocated, the circulation delay information of the reference signal, and the index of the group.

The present invention relates to a method for mapping a hybrid ARQ indicator channel, which is transmitted to a downlink in a wireless communication system, to a frequency and a time resource.
Abstract:
Disclosed is a method for transmitting an ACK/NACK signal for an HARQ (Hybrid Automatic Repeat reQuest) in a CA (Carrier Aggregation) system, the method including obtaining at least one transmission resource among first and second transmission resources; configuring a first table showing a relationship in which a combination of at least one of the first and second transmission resources and modulation symbols is mapped to an ACK/NACK signal, and transmitting modulation symbols corresponding to a transmission target ACK/NACK signal in the first table by using transmission resource corresponding to the transmission target ACK/NACK signal in the first table.

Abstract:
The present application relates to a method for transmitting and receiving hybrid ARQ information transmitted via a downlink in a wireless communication system. In particular, the method for a transmission point to transmit hybrid automatic repeat request (ARQ) information in a system having multiple transmission points comprises, as technical features, the steps of: transmitting virtual cell identity (ID) information to a terminal; and transmitting, using a resource which has been determined on the basis of the virtual cell ID information, hybrid ARQ information for indicating whether uplink data transmitted from the terminal has been received or not.
Abstract:
The present invention relates to a method and device for transreceiving cell-selective signals in a multi-component carrier system. The present invention provides a method for transreceiving cell-selective signals, and the method comprises the steps of: configuring, in a terminal, a sub serving cell belonging to a first band; setting one of the sub serving cell and a main serving cell as a mute serving cell and the other as a valid serving cell, in an inconsistent subframe in which a first TDD uplink/downlink configuration of the sub serving cell is different from a second TDD uplink/downlink configuration of the main serving cell belonging to a second band that is different from the first band; and transreceiving a scheduled signal to and from the set valid serving cell.
Abstract:
An apparatus and a method for allocating resources for transmitting an HARQ ACK/NACK signal for a downlink subframe using a PUCCH format 3 in a time division duplex (TDD) system using a single carrier are provided. Since the resources are allocated through a resource indicator transmitted using a power control field transmitted on a PDCCH of the downlink subframe, the resources for transmitting the HARQ ACK/NACK signal may be allocated by effectively using resources allocated to a duplicately transferred control signal.
Abstract:
The present invention relates to a method of receiving transmission mode information on a user terminal in an inter-band TDD transmission scheme. The present invention includes, at a base station controlling two or more bands with different time division duplex (TDD) settings, receiving a user terminal function information message that includes transmission mode function information on the user terminal in the two or more bands, and setting an element carrier aggregation environment of the user terminal to match the transmission mode function information, wherein the transmission mode function information includes information on whether the user terminal operates in a full duplex of half-duplex mode in the two or more bands.

The present invention relates to a method and apparatus for applying PUSCH/PHICH scheduling timing in inter-band TDD transmission schemes. According to an embodiment of the present invention, the method for applying PUSCH/PHICH scheduling timing in inter-band TDD transmission schemes by a base station for controlling two or more different TDD bands includes the steps of: selecting a reference Physical Uplink Shared Channel (PUSCH)/Physical Hybrid ARQ Indicator Channel (PHICH) scheduling the timing of a UE, which supports cross-carrier scheduling by using two or more serving cells; transmitting instruction information for instructing the selected reference PUSCH/PHICH scheduling timing to the UE; and allocating an uplink and/or transmitting a PHICH to the UE according to the reference PUSCH/PHICH scheduling timing.
